NMS - NH3 Analyzing System

The IAG NMS analyzing system is a 191 °C heated extractive diode laser ammonia detection system.

This very compact and light system can be used in a wide variety of applications.

Two sample gas inlets, two analogue output instrument, a built-in gas inlet pressure regulator, a heated sample gas filter, an integrated purge function, a span gas connection and any kind of communication option you might eventually like are basic technical features.

Setup and operation are kept as simple as possible without sparing an operation software with all functions the advanced user would expect, including alarm parameterisation, calibration as well as open communication settings.

The operation takes place via touchscreen directly at the device or via communication interfaces such as AK, RS232, Modbus or Profibus.

Reponse Time:
Analysing components like NH3, which are very difficult to detect, require measuring systems that provide optimal response times. IAG has been developing heated pre-filters since 1998 and has worked ever since to create sampling modules and measuring systems with minimum internal volume, optimised gas flow, uniform heating and special surface treatment. Therefore, this system has the ability of realising very short response times.

Another important thing to mention is the maintenance friendliness of our products. Annual maintenance can be easily done by the user and wear parts are available for very reasonable prices.
